The genus Acacia formerly enclosed roughly 1300 species, about 960 of them indigenous to
Australia, with the remaining distribute around the tropical to warm-temperate regions of both hemispheres, including
Europe, Africa, southern Asia, and the Americas. However, in 2005 the genus was separated into five individual genera under the tribe "
Acacieae." The genus Acacia was maintained for the majority of the Australian species and a few in tropical Asia, Madagascar and Pacific Islands. Most of the species outside Australia, and a small number of Australian species, were reclassified into
Vachellia and
Senegalia. The two final genera,
Acaciella and
Mariosousa, each contain about a dozen species from the Americas.
